Circlip Internal 8mm - Pack of 5

Internal circlips (also called internal retaining rings or snap rings) are precision-formed rings that seat into a machined groove inside a bore or housing, holding bearings, bushes, gears, shafts and other components securely in place. This circlip is made from spring-tempered carbon steel to DIN 472, suited to general workshop, industrial and automotive use.

Where this product is used

Internal circlips are used wherever a component needs to be retained inside a bore or housing without welding, bolting or machining a shoulder — the ring seats into a machined internal groove and holds the component captive from the inside.

• Bearing, gear and shaft assembly retention inside housing bores in gearboxes and general industrial machinery.
• Automotive and agricultural drivetrain component retention, including gearbox and transmission assemblies.
• General engineering and production-line maintenance wherever a removable internal retaining ring is needed.

Key specifications

Selecting the right option

Confirm internal vs external before ordering — an internal circlip (this product) fits inside a bore or housing; an external circlip fits around a shaft. Match the circlip to the exact bore diameter for your application and check it against the machined groove dimensions in your equipment drawings or the manufacturer's spec sheet. Where the application involves washdown, marine, food-grade or outdoor corrosion exposure, choose our 304 stainless steel internal circlip instead of this standard carbon steel version.
